Fox News’s Tucker Carlson revealed Thursday that Marie Yovanovitch, former U.S. Ambassador to Ukraine, communicated through her personal email with a Democratic congressional staffer, contradicting her deposition on Capitol Hill last month.

Yovanovitch, who’s a key witness in the Dems’ impeachment inquiry, told Rep. Lee Zeldin (R-NY) that she never responded to an Aug. 14 email she received from the staffer, Laura Carey.

But emails obtained by Carlson’s show reveal that wasn’t the case.

“Before the contents of the whistleblower complaint were known publicly, a Democratic congressional staffer contacted the former American ambassador to Ukraine to discuss what the staffer described as ‘quite delicate and time sensitive questions,’” Carlson said.
